I need to figure out what the abbreviations on this pcb stand for to try and re-wire this thing after someone cut all the end connectors off. Any help would be greatly appreciated and applied to my project. Thank you in advance11760AAC-0F2A-4F1A-80D7-3B19B450D7D0.jpeg11760AAC-0F2A-4F1A-80D7-3B19B450D7D0.jpeg70A25D5E-220C-44AC-AB99-32E96850A808.jpegEF042683-5621-4DBA-AA99-75DC1BFEFF5D.jpegD8C3E625-C93D-4E55-861A-AC58B5ACA8C9.jpeg7CA47D50-5CA6-4CE4-8B31-9BAB690674AD.jpeg
 
Are the remaining wires still grouped together or all separated? Some will be fairly easy to identify even without tracing them to the circuit board, especially if they are grouped (5/6 wire bundle would be for the hall sensors; 3 wires can be throttle or PAS or sometimes a 3 speed switch; 2 wires could be brake cutoffs, cruise, etc.). If you can identify the easier ones first, it will be simpler to trace the rest.
 
Some best guesses (since consistency isn't a common property of these things); keeping in mind that some of them, if connected wrong, will damage or destroy things:

HW HV HU motor hall signals. H+ hall power. H- hall ground.

VM1 (thin red / orange wire) is probably the LVPS input (KSI), connect this to battery + to turn the controller on.

1:1 is probably a speed limiter, when connected to ground it either turns the limit on or off.

B / S1 are likely inputs for either PAS or throttle (one for each), but the S1 could also be an input that gets grounded to turn on a "boost" mode (S1 and S2 would tthen be the two wires used for a three speed switch, where grounding either one enables low or high mode, and no connection is mid / normal mode).

Don't know what the TS+ and TS- are; best guess is data lines for a display. If one reads 2.5v and the toher either 0V or 5v when you get the controller turned on so it produces 5v at the +5V labelled pads, then they are probably data lines.
 
I've been studying these control boards relentlessly.Night and day asking the internet and every kind of way for refrazing my sentences and trying words from different countries. I still cannot match up the SW900 display with this Motoberry 40 to 80v controller it does say it has a 41v lvc.
(low votage cut).so I only have a 36v battery that charges up to 40.9 volts. No matter what I do I can't not get more than 3.6v Everywhere I check. Lvc could be the problem or not having the same plug as my last controller. I though I could still supply power enough to test more than I'm able to. My question is, is how would you hook up the not SW 900 display plug to a controller that does not have the same plug coming out of it? I think I had it right. But I could not find a place.
For the yellow transmission line, I figured I'd power it up.See a few things and then try to figure it out.But I got 0 power on the display
Except for the 3.6v at some areas. So I got power from the alarm plug.I connected the green SW 900 to the green line on #16 green and then the blue line to num 1 .But yellow's not hooked up and I don't know what or where a "TX" like my other controller had. Nevertheless , I don't get any power to display help , please

You can't. The controller doesn't support a display, and the SW900 only works for specific controller brands, and yours isn't one of them.

I can use this without the display.In other words , if it would have to have that same plug
UPDATE
I'VE COME A LONG WAY SINCE AUGUST 4TH IT IS NOW MARCH THE 9TH. I've learned as much as I could and still trying to learn asking questions I came across my post thinking someone else wrote this anyway TS is a temperature sensor to my younger self..
